Optimizing a demand-responsive feeder system for low-demand areas
Book Contribution - Book Chapter Conference Contribution
Efficient public transport systems are essential for the dynamism of medium and large cities. With
the growth of urban areas around large centers, new neighborhoods emerge in the suburbs and
pressure the public transport system. A limited solution is to extend the system with feeder lines.
However, in the last decades, demand-responsive systems emerged, complementing traditional
systems and providing efficient transportation services for users and operators. We introduce a
demand-responsive public bus system that considers shortcuts and detours and modifies the
departure times of a feeder system, based on the current demand. This system contains a
recognizable backbone, but it is not fixed. The operation is optimized, using a memetic algorithm,
for each operation period in order to reduce passenger travel time. The optimized system in our
experiments reduces passenger travel time with 18 to 38% compared to a traditional system
operating the same network with fixed routes and timetables.
